Maybe worth asking: how are you computing MPG? No offense to anyone on the boards here, but some guys use...um..."scientifically questionable" methods. The only way to be accurate is to note your starting mileage with a full tank, then every time you fill up you add up all the total miles driven since the starting point and divide by the total of all the gallons pumped, keeping in mind that you still have odometer error to worry about with non-stock tires, etc. Using this method I see variations of 2-3 MPG from fill up to fill up- partly due to the differences in just how full I get the tank. But doing the long-term average minimizes the margin of error, giving you a more accurate MPG number.
I've put 8k miles on my '96 in the last 2 months running all over Los Angeles and Southern Cal, and my overall average is 19.8 (CCSB, 4X4, ZF5, 3.55)

With mileage like that, you have me wanting to swap the same setup into my truck! Must be a lot of highway miles?

Nate,
Darin is towing I think ~16k with an auto and 3.55s with no problem. He says he runs at like 75 to keep it more in the power band. I got the same mileage with auto and 4.10s as I do with zf and 3.55s but I just like the truck better. If you just have the option and want optimal mileage I can't see a combo better than the auto and 3.55.

So in comparing the two, how is the mileage difference between the 3.55s and the 4.10s? At this point I can put pretty much any combination of 3.55/4.10 and auto/ZF together and make it work, so long as everything in the parts truck is good. What would be your ideal setup for a DD that is also a workhorse for occasional towing and hauling?
Yeah all my mileage is more or less hand calculated using the above described methods. Actually I have an app on my phone that I use to do the calculations now, but it does the same thing. It's just handy because it can keep a log of any service I do to the truck as well. Oil changes, filters, mileage, it's all in one spot. Not the best app ever, but it works for now.

That's good to hear. I'm not sure the ZF is going to be an option. My wife drives the truck maybe 4-6 times a year and has told me that she won't even try to drive it with a manual transmission. While I am not sure whether that is a good or bad thing (LOL) I am pretty sure it would make me the bad guy if I swap in the ZF. What to do, what to do.....
In some ways I would really like to have the ZF, but I can see the benefits of either one (ZF or E4OD). One thing is for sure though, you can buy a lot of clutches for the price of a rebuilt auto!

Ha yea luckily i dont have one of those yet that thinks she needs to make decisions for me. I think a nice auto would be handy alot of the time, im still young though and enjoy rowin. If you do the swap i would suggest using the ZF5-47, it is rated for a little more torque and is a little heavier duty from what i have read. One day i will have to tear into one of the two i have and then i can see what the real inner workings are between them.

Yeah, she doesn't think she needs to make the decisions for me, but it's hand having two vehicles that she can drive. Every once in a while it comes in handy.
If I do the swap, it will be with the ZF5-42 out of the truck I am bringing home tonight. I would rather have the 47, but hey, you got to use what you have right!?

Oh and as an attempt to redeem myself from shamelessly derailing this thread, here is a recent thread in which the topic of fuel economy was covered extensively.

1995 7.3 overheating problem--PLEASE HELP
Anyone have any valid ideas that might be able to help me? My 1995 F350 with 7.3 turbo diesel is overheating when I pull a load. It started when a leak was noticed from the water pump. That was swapped out along with the thermostat. Then the overheating began. Another water pump was swapped in along with thermostat and sensor. Same problem. The engine block sensor was swapped and still have the same problem. When hot, both the upper and lower radiator hoses are about equally hot. Before the water pump swap, this truck would pull the same load without difficulty. Now, at 60mph, the gauge shows hotter than the L in "normal" and at 65 it's about halfway between the L and the white hot mark. My mechanic is baffled. The diesel mechanic at a large Ford dealership is baffled. I'm wondering if maybe the transmission fluid could overheat the coolant as it travels through the radiator chamber and cooler. Anyone know if that is a possibility? The mechanics don't think so but maybe... HELP!!!
